Cancer refers to a class of diseases in which uncontrolled cell division in a specific tissue causes the growth of tumors or even the spread of metastases to other locations in the body. According to the world health organization (WHO), cancer will be the most common cause of death worldwide in 2010. The trait affects people of all ages, but is highly associated to environmental factors such as tobacco consumation, diet/obesity, exposure to radiation or polution, stress and the overall lifestyle.The genetic factors manifest in two classes of genes: oncogenes promote tumor growth by allowing hyperactive cell growth/division or protecting against programmed cell death, and tumor surpressor genes, which tend to be inactivated in cancer cells. Since a successful treatment highly depends on a diagnosis in an early stage of the disease, methods to estimate and predict the disease risk are needed. In particular, a better understanding of the mechanisms that activate, inactivate or regulate oncogenes and tumor surpressor genes is of outmost importance, and with the recent development of next generation high-throughput sequencing technologies improved classification and personalized therapy becomes more and more feasible.
MicroRNAs (miRNAs) are non-coding RNAs about 22 nucleotides in length that regulate a variety of genes. In recent years, strong evidence has been collected that miRNAs play an important role in cancer development and that miRNA expression profiles can be used to classify and rate human cancers. In collaboration with the Cancer Genomics group at the Max-Planck-Institute for Molecular Genetics, we applied statistical modelling techniques to search for known and yet unknown miRNA candidates potentially associated with three different development states of colon cancer.
